Found this at an old cellar hole. It is brass or bronze or some such metal. The decorative piece on the left was obviously made to clasp something thin -- the dot in the middle is a very small, delicate pin that would have gone through whatever was being held in between the top and bottom. The two "spots" on the long part are where it was attached to something else (looks like it was soldered to something at those spots)
Maybe a hinge for a purse? Small jewelry box?
